https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D271134 Marcin Cie=C5=9Blak <saper@saper.info> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |saper@saper.info --- Comment #11 from Marcin Cie=C5=9Blak <saper@saper.info> --- There is something strange with Fwcfg types. I think this should be a separate section block... Boot ROM device backends =E2=80=A2 romfile[,varfile] Map romfile in the guest address space reserved for boot firmware. If varfile is provided, that file is also mapped in the boot firmware guest address space, and any modifications the guest makes will be sav= ed to that file. Fwcfg types: fwcfg The fwcfg interface is used to pass information such as the CPU count or ACPI tables to the guest firmware. Supported values are =E2=80=98bhyve=E2=80=99 and =E2=80=98qemu=E2=80= =99. Due to backward compatibility reasons, =E2=80=98bhyve=E2=80=99 is the default option. W= hen =E2=80=98bhyve=E2=80=99 is used, bhyve's fwctl interface is used. It currently repor= ts only the CPU count to the guest firmware. The =E2=80=98qe= mu=E2=80=99 option uses QEMU's fwcfg interface. This interface is widely used and allows user-defined information to be passed to the guest. It is used for passing the CPU count, ACPI tables,= a boot order and many other things to the guest. Some operating systems such as Fedora CoreOS can be configured = by qemu's fwcfg interface as well. --=20 You are receiving this mail because: You are the assignee for the bug.=
